System-wide sandboxing framework - sandbox-app-launcher

[Patrick]

Switching to ALSA

The honorable @madaidan has pitched this suggestion because it is still updated and less of a problem to isolate with sandboxing. Questions are : is it easy to uninstall pulseaudio? Is there anything important that depends on it? How much space do we save? - If none then maybe it is not worth the bother. I remember at some point TBB refused to use anything but pulseaudio so this needs to be re-examined. Discuss.
